Page 8: Installation Considerations
• Avoid all pipe locations where the flow is pulsating, such as in the outlet side of piston or diaphragm pumps. • Avoid locations near equipment producing electrical interference , such as electric motors, transformers, variable frequency drives, etc. www.h2flow.net... -
Page 9: Special Notice
• Install the meter with enough room for future access for maintenance purposes. • The magnetic meter isolating liner, whether it is PTFE or Rubber, is not intended to be used as gasket material. Standard gaskets (not provided) should be installed to ensure a proper hydraulic seal. When installing the gaskets, make sure they are properly centered to avoid fl ow restriction or turbulence. - Page 10 Stray AC or DC currents through the fluid or instrument can produce noise signals that may in turn interfere with the relatively low flow signals generated in today’s modern pulsed DC mag meter. H2flow Controls provides a variety of elements (ground straps, ground electrodes, ground rings) and directions for the standard grounding of the mag meter.

- Page 32 Sensor signal sensitivity: at a flow rate of 1 m/s, the sensor outputs 150µV - 200µV; For the FaraMag FM750 electromagnetic flow meter converter, four (4) 62.5mA currents are used in the excitation circuit to form 250mA. Each 62.5mA current is controlled by a 20Ω precision resistor. Therefore, the user can choose a different magnitude of the excitation current by changing the number of precision resistors.

Therefore, the pulse output frequency should be limited below 500Hz (when the pulse width is 1ms). If the pipeline fl ow is small and the pulse equivalent is selected too large, it will take a long time for the instrument to output a pulse.
